The IR illuminators are concealed under the front cover plate 708, but light generated by the IR illuminators can still penetrate the front cover plate 708 to illuminate the field of view of the doorbell camera 106. In some implementations, the doorbell camera 106 further includes an ambient light sensor ALS assembly 714 at least partially disposed within the lens assembly 704. The ALS assembly 714 is configured to measure amount of light entering the lens assembly 702 from an ambient environment surrounding the lens assembly 704. Part of the ALS assembly 714 is exposed to incoming light, and therefore, visible from a front of the doorbell camera 106 in the lens assembly 704. The ALS assembly 714 is configured to compare the measured amount of light to a threshold illumination level, and the doorbell camera uses corresponding comparison results to determine its operation mode between a daytime mode and a night mode. Specifically, in some situations, the ALS assembly 714 determines that the mount of light entering the lens assembly 702 exceeds the threshold illumination level, and the doorbell camera 106 enables the daytime mode in which the IR illuminators are turned off.alarm security system
